In the Clinton impeachment we decided that perjury isn't an impeachable offense, at least when it's basically about a president's private life and not the essential parts of his job, treason, murder, rape, subverting democratic elections, corruption ... .

But what about plain old criminal prosecutions? if presidents and candidates don't get prosecuted for obvious perjury either, then that tells everyone else to disregard that lying when testifying it's illegal and dangerous. And it gives lawyers and judges another reason not to believe what anyone says. Testifying to a court -- whether on the witness stand, in a deposition, or a written, notarized affidavit -- is under oath and "under penalty of perjury."

Newsweekhas published clear proof that Donald Trump either: (a) lied in a deposition in a case against an ex-employee, about a failed attempt to bribe Florida Gov. Jeb Bush, or (b) lied about it to Bush's face in the second debate. Or both. (Even if bribe is the wrong word, that doesn't affect the specific question that the lie and contradiction were about: Whether Trump was trying to get Bush to reverse his opposition to casino gambling when he hired the Defendant to get Florida to allow him to build a casino and hosted a fundraising event for Bush.)
